Please add the option to add/set wallpapers as app UI colour scheme and in to the background of message threads and the individusl, message threads. Also the option to set transparency for the UI and message/thread backgrounds.

Instead of just using the Sim Number on dual sim devices, please also add the option to choose along with the current option to choose Sim Number 1, 2, also add the option to choose Network Name instead and the option to have icons such as Home, Work/Office, Personal etc…. similar to Samsung Messaging app that allows iconisation on dual sim devices (inside dual sim management option).

Finally, please study the Messaging App Yaata and others to get additional options that are functional without confusing the UI too, much like Yaata.

Overall great, simple app. Thank you.
